Step 4: Writing
Students will be asked t write an argumentative essay f garbage srting recycle
Sample:
Recently, garbage srting recycle has becme a fcus f the sciety. Sme peple argue that it’s nt necessary t d this. Others, in the cntrast, think we shuld take actins right away, fr sciety prduces a large amunt f rubbish every day. And I agree with the latter.
Firstly, rubbish classificatin can reduce the amunt f rubbish and the rubbish pllutin t the envirnment. Secndly, it is a scientific and effective way t manage rubbish. Apart frm that, by classifying rubbish it allws us t recycle resurces, which will imprve the quality f ur living cnditins and help the envirnment.
In clsing, I definitely think we shuld start the activity--- garbage srting recycle immediately. It will surely be beneficial t bth ur mankind, but als the envirnment.
